Abstract
PURPOSE: To select an optional output state only by changing the polarities of a DC power source connected to a power source terminal.
CONSTITUTION: When a body 11 to be detected is present, a detection output is high and an input 12a is also high; when not, the detection output is low and the input 12a is also low. When a terminal 7 is connected to the positive side of a DC power source and a terminal 6 to the negative side, the potential of an input 12b is high. Therefore, an output appearing at the output terminal 12c of an exclusive OR circuit 12 has the same polarity with the input 12a. In this case, when the body 11 to be detected is present, an output transistor turns on and when not, it turns off. If the terminal 6 is connected to the positive side and the terminal to the negative, on the other hand, the potential of the input 12b is low and at the output terminal 12c of the circuit 12, a signal applied to the input 12a appears being inverted. The output transistor turns off when the body 11 to be detected is present.
